This invention relates to safety devices for feeding material to thesqueeze rolls of wash Wringers and the like.

The main objects of my invention are to preclude the possibility of thehands being caught between and drawn into the squeeze rolls ofwringers;- and to attain this end through provision of a simple,inexpensive and easily operated device forthe purpose, '0 capable ofready application to all standard types of wringers. 1 her objects andattend-ant advantages of this mvention will appear from the detaileddescription following when taken in connec-- 5 tion with the attacheddrawings, whereof Fig. I is a perspective View of a conventional type ofwringer equipped with my improved safety feed, the latter being shown inre tracted or loading position.

30 Fig. II is a cross sectional elevation of the wringer with the partsof the safety feed positioned to correspond with Fig. I.

Fig. III is a perspective view, similar to Fig. I, showing the safetyfeed in the ad- 2'5 vanced or feeding position; and,

Fig. IV is a cross section like Fig. II, but with the parts of thesafety feed positioned as in Fig. III.

From these illustrations it will be seen that the safety feed of myinvention comprises a feedmember '10, the same being movable, ashereinafter noted, from the retracted or loadin position of Figs. I andII, to the ad- Vance or feeding position of Figs. III and IV inpresenting the material M, which is to be wrung, at the bight of thecompanion squeeze rolls R, R of the wringer, comprehensively indicatedby the letter 'W. As shown, the feed member embodies a hori zontal bar11 which is angular in cross section, and, beneath the forward edge .ofsaid bar is .a freely revolving auxiliary progressing roller 12. At 13,the bar 11 has pivotal connection with the ppe-r ends ofsupporting arms14 which are fulcrumed at the :bottom to brackets 15, secured to theverticals of the wringer frame F at one side by screws 16. The feedmember 10 ismoreover formed with upwardly reaching extremities 17 whichextend forward somewhat at the top as at 17a and carry lateralprojections 18 arranged to engage vertical slots 19 in ears 20 of thebrackets 15; Rea'rward' ofthe projections 18, the extremities -17 of thefeed' member 10 afford pivotal conneetionfor' a hanger 21 with droopingside arms 22 integrally joined by a transverse rod 23 whereof the endsnor- V mally rest on the forward extensions 17a ofsaid extremities.Suspended from the hanger 21 is a finger guard 25 constituting a shieldacross the fr nt of the squeeze rolls R','R of'the wringer W. Theoutward swing of the, feed member 10 is limited, as shown in Fi s. I andII, through contact of the projections 18 on the extremities 17 with thebot- 85 toms of the slots 19 in the brackets 15; while the inwardswing'i-s limited through engagement of stops'14a on the'arms14 with thewringer frame asshown in ig'. IV.

The operation of the device is as follows: 7

' Withthe feed member 10 retracted as in F igs.

I and I theleading end of the material M is laid on the bar lljsoa's tooverlap the auxiliary progressing roller "12." The feed member 10 isthenmoved inward by hand to the position of Figs. III and IV with the resultthat the lapping end of the material M is pressed, by the auxiliaryprogressing roller 12 against the lower squeeze roll R of the wringer W.Through motion thereby'induced in the roller 12 the'fold of the materialM is advanced "so as to be caught in the bight between the roll It andits companion R. In this connection it is to be particularly noted thatthe feedmember 1-0 is maintained under the influence-of gravity both inthe retracted or loadingpositionand the advanced or feeding positionbyvirtue of the swing of the supporting arms 14 to opposite sides oft/hevertical or dead center. It is moreover'tobe noted that throughproportioning of the various interconnections involved, the finger guard25 is ordinarily littedjust sufficiently to clear the material it ispresented to thesq'ueeze rollsR, incident'to the inward swing ofthlefeed member 10'. I

When necessary, access may be had to the squeeze rolls R E of thewringer W' from the front by lifting the hanger 21,- as shown in dot-anddash "linesin 'Fi-g'. II, thereby to tween the lugs 27 and parallel lugs29 be neath, said slots being open at the back as indicated at 30.Withthe projections 26 thus 3 freed, the guard top of its pivots, 21 inturn swung rearward in a manner entirely obvious from Fig. 11.

' The wringer chosen for the purpose of illustration hereinjis. of areversible type comcan be swung over the mon in connection with modernwashing machines, it being mounted to swing horizontally about a columnO and provided with a drainchute S which is oppositely tiltable as shownin dQt-and-dashl-ines in Fig- II. To enable use ofthe safety feed 10 inthereverse position of the wringer'W if desired, the other side ofthewringer frame maybe drilled and tapped to take the bracket screws 16incident to transposal ofthe feeddevice to that side of said .frame. j II 7 Having thus describ d my IlIlVGIIi' lOIM'I claim; a g1 1 A safetyfeed for. wringers having squeeze rolls comprising ahorizontally-pivoted gravity-influenced feed member with anassociatedfreely-rotatable roller for presenting material tobe wrung atthe bight of the squeeze rolls, afinger. guard .for shielding the rolls,and means operatively coaordinating said guard with the feed member-forinducec movement to clear the material concurrent with its presentationto the wringer squeeze rollspf 1 2.
